As far as a shell script is concerned, an environment variable is just a variable that happens to be inherited from the environment, it doesn't change the behaviour of that variable.

So to understand what the code does, you don't need to know which "type" of variable it is, only that by that point in the code, there might be a variable with that name. You then need to know this fact about the [ (aka test) command:

STRING: equivalent to -n STRING

and

-n STRING: the length of STRING is nonzero

So all [ "$MYSQL_DATABASE" ] means is "is the length of the $MYSQL_DATABASE variable more than zero at this point in the code?"

Whether this variable is expected "before" the script runs (e.g. preset as an environment variable) or calculated "inside" the script, you can only find out by reading through.

The command that works in Git Bash is using input redirection. That doesn't work in Powershell, as < is reserved for future use. Since Powershell doesn't parse < as redirection, it passes string literal mydb as the database name. Thus, the error message.

To execute the script file, use -e "source script.sql" for invoking mysql client in batch mode processing.

The first image issue could be because you imported the image incorrectly. The docker import command is the inverse of docker export which works on container filesystems rather than images with image metadata. Instead you should run docker load with docker save to transfer images. If that works correctly, you will see an entrypoint defined in your image and that entrypoint is what docker should try running with the command value as an argument to the entrypoint:

hmm, looks like the issue is with privilege user for the database table, Try to create a privileged user in your database named root. After that please check again

========================================================================================== try these queries in your databse:

The article you have followed is outed and also running container and the change password is not the proper way when working in the container. With Offical image, you can set using environment variable.

use below command and further details you can find on Mysql Docker hub.

You need to use the --protocol=tcp in your connection url.

There is no default password, try login in using:

Try to change the url into this your properties file

jdbc:mysql://mysql-docker-container:3306/kamienica

try "mysql --port=3307 -h 127.0.0.1 -u -p" from client if no
